Hi! I've been experimenting with a few file formats that can be attached to the SL Community forums. We all know about JPEG and GIF. However, these days, there are a gazillion more (and better!) formats. For instance, this is a file uploaded in Animated PNG (APNG) format, which is allegedly supported on almost every browser except IE (if you just see a static image, it means your browser doesn't support APNG): Naturally enough, there is no documentation about the support of APNG. This is not very surprising: after all, APNG files use the very same .png extension (and graciously fall back to the first frame...). Thus, APNG should work on any website that doesn't resize the image or convert it to an 'internal' format. There are some exceptions, depending on the kind of backend is used. For instance, if phpBB is installed with ImageMagick as the resizing engine, ImageMagick will have no issue with dealing with APNG correctly. Other graphical backends may simply not support anything beyond the first frame (while happily accepting GIFs — others will not even allow that, of course). The trend, however, is not only to resize images (sometimes on the fly, for the benefit of mobile users), but to convert it to a completely different format, thus destroying the original image in the process, and whatever 'special features' it might have included at some point. The reasoning behind this is the fear of hackers surreptitiously exploring some bugs (usually memory buffer allocation) in order to trick the webserver to run some sort of malicious software. While this is harder to accomplish than one might think, the truth is that image resizing and/or format conversion will get rid of any malicious code (possibly trashing the image in the process, but hey, that's what you deserve if you're attempting to crack a system...). Thus, restricting image file formats to just a few, or allowing a few more but ultimately converting everything to a single format (such as plain, old, boring, inefficient JPEG...), is a simple (but reasonably effective) method for virus & malware destruction. Sadly, it also means that the options given to users is limited. JPEG, GIF and even PNG are ancient, obsolete formats. They just have the advantage of being widespread. Nowadays, however, we have far better encoding systems. Just try to convert a WebP or HEIF image to PNG, and watch how much the file size will grow. Reversely, convert an image (even a PNG already minified by TinyPNG) to WebP or HEIF (or even to the venerable JPEG2000 — used internally by Second Life itself!), and you see how much you can save that way — which is a reason why those formats were designed in the first place, namely, to address ever-growing image resolution sizes. And what about vector images? SVG, a standard for over twenty years, is supported by all browsers — but almost no applications. Why? Very early implementations of SVG — which has the ability to run JavaScript or other embedded code) — were deemed 'dangerous' (because, indeed, some people have managed to take over systems by merely uploading a SVG), and so, it's rare to find a software that supports it from scratch (even WordPress doesn't support SVG by default, although there are tricks to allow it to do so). Again, the 'danger' comes from an excess of caution. Because SVG is a text format (more precisely, it's a XML file, conforming to its standards), it can very easily be parsed for any embedded code, which can be stripped out, at absolutely no loss in functionality or quality. SVG is also an animation format: you can do pretty complex animations inside SVG, without the need for anything else, and let the browser render it pixel-perfectly at whatever resolution the user wants — that's the beauty of vector images! But... well, because it was felt to be 'dangerous', this simple, compact, efficient and extremely powerful file format is usually 'banned' from being uploaded to most software out there :-( And what about video? Well, I can imagine that the major problem with video is its size. That's especially true with the most universal of all formats, MPEG4. On sites supporting it — not the case of the SL Community forums! — videos tend to get re-dimensioned during upload, and automatically converted to MPEG4 (this is how YouTube used to work, for example). That's all very nice, but there are far better formats, both in terms of what they can support (e.g. Matroska containers can have several audio and subtitle channels, automatically selected to match the browser's language settings), and in how well they can compress video (such as Theora or WebM), even with lossy quality, but giving much better results than Plain Old MPEG4. LL's limitation on 4.88 MBytes for the file size is not really much for MPEG4, but it goes a long way with the more contemporary formats — you can both get better quality and longer videos on Theora/WebM/H.265, etc.) It's incredibly rare to find video support to anything else besides MPEG4 — if at all — and when it is supported, it just goes into a queue, scheduled for internal conversion to... MPEG4, thus losing all the savings made in the first place! I couldn't figure out how to upload any video file format to the SL Community Forums. I wonder if there is an (undocumented) 'trick' to make it work? AFAICS, the answer is 'no'. An alternative, of course, is to embed a link to YouTube (that works at the cost of not having autoplay...): The same approach apparently also works for Vimeo: ... and possibly a few more popular sites. However, if you wish to embed your own video... there seems to be no simple way to accomplish that, unless you use one of the 'supported' providers. Anyway, this was just a rant... a friend asked me what kids of file formats the SL Community Forums supported. 'Not many', it seems. That's why I seriously suspect that she'll just stick to the plain old (animated) GIF format to upload small-ish 'videos'... Unless anyone could point me to an up-to-date list of supported image and video formats?...

Second Life al subir la imagen no deja subir imagenes mas grandes de 2040 Pixels, sin embargo las veo borrosas, le he subido la resolucion interna sin embargo sigo viendo borroso el resultado una vez en Secondlife, de alli que pregunte cual es la resolución recomendada para trabajar con texturas de alta calidad o detalle en photoshop para el metaverso, de antemano GRACIAS

I have a Single image i'd like to turn into a Mesh object, it don't need a texture as it's gonna be black or white, if anyone can do this please contact me in world to get the image and we can talk about how much you'd charge. thanks Blade Reluin

Hello! Help to create an image like in the picture! especially interested in hair. advise a similar model? Pink skin also interesting.

The title says it all. I always get blurry textures even when I bake it on a larger image, soon as I downsize it to 1024 or 512 depending on size of the object I get a blurry result. Sometimes it messes up the image What should I do?

So, I've recently become a texturer, mostly creating specular and normal maps, sometimes diffuse maps, and usually for buildings. Now, I've also recently learned of the difference between a vector image and a raster image. So tell me - would I be able to create vector textures? Are they possible? If yes, why in the world is no one using them? If no, why can I not do this? I'd love to hear feedback and get answers!

Please Help. I will attache a screen shot of what i see.. Thank you

hi guys really needing some help here i don't have the option to upload images to my market place listing. ive opened a support ticket, they said to try safe mode. ive done that with firefox, chrome aswell as internet explore, ive even testing my hubbys computer and even my cell phone ad the option is not there. so once i replied back to my ticket basically i would told to come here instead to ask for help.

I can't seem to figure out why this is happening. Would really like some help ^^

Hi all, Im trying to upload an image to my profile feed, but no picture is working, it keeps showing this error "failed to upload image to your profile" no matter how many retakes or how many times i try to reupload it, i am using second life viewer if thats of any significance. Any help?

I made some screenshots from game and save in my PC as jpg files. I want post this pictures on my wall in second life? How to do that I can upload in folder in second life, but how to post on profile? Thanks
