How to remove background of a picture?

[Chabelita14]

I created a nice text in adobe photoshop and removed the background so only the text shows. I saved it in both photoshop form and jpeg form. When i uploaded the jpeg form with the remove background in photoshop it shows up with a white background in sl. How can I make it so only the letters show without the background?

Export as a png file with transparency checked

There is no need at all ever to upload pictures to SL as a JPG file.

As Chic told use PNG file. Even better is TGA file where you can easily control whether to show the transparency or not.
24 bit TGA file = without transparency, 32 bit TGA file = with transparency.

In a PNG file controlling the transparency could be a bit trickier if you don't "how stuff works". :smileyhappy:

As PNG and TGA file are lossless there is no quality loss in those files.
JPG file is lossy format, there is lways some quality loss.

as an add on for what Coby wrote.

.jpg will flatten your image + there is no alpha channel in this format

why 24 or 32 bits?

Each channel R(ed), G(reen) and B(leu) has 8 bits on top of that there is an alpha channel that also need 8 bits

RGB = 8+8+8 = 24 bits no alpha channel

RGB+ Alpha = 8+8+8+8 = 32 bits texture with alpha channel

So pls mind: if you would save a texture that is not to be suposed to have an alpha channel you do not want to save this as a 32 bits. Even though it might be not immediately visible you take a high risk that the texture will "bleed". It becomes inmediately visible when you make this channel visible in sl. (crtl+alt+t if I remember well)

This is a mistake I've seen quite often and too basic to be allowed.

.png or .tga.... well there are a lot of discussions around this choice among very advanced PS users. Personally I prefer .tga under other for the reason Coby mentioned.

The only reason I can think of where you would want to use a JPG is:-

If you want that texture to be referenced from a web page which calls up on the UUID of the texture within SL, you'd better upload it as a JPG or it doesn't show up on the web page.

An example of this is an inworld vending system which is web managed.

I don't know why but it doesn't show if uploaded as a PNG but I can't say i've tried it with a TGA as the source.  Odd really since they're both converted to JPG2000 but there's clearly some bit that gets converted differently.
