You need to explain more clearly what exactly you are trying to do.  What did you just sign up for? Have you downloaded an SL client and logged in?  Did you sign up for Premium and choose a Linden Home?  Too many unknowns to help you.

Vector such as an EPS or the original format can be resized in photoshop or similar ap and   saved as  PNG  and then uploaded to SL  thats the reason it should be in vector so that the owner  can  resize it to anything without affecting the quality. A bitmap file can only be sized down not up unless you want it to go nasty. Logos get used over a long period of time and used in many sizes so it's important to get the origial in vector.

When uploading to Sl the best format is PNG it uses less memory than none compressed bitmap images  and less compression articacts than other compressed image formats.

In whatever file format (JPG, PNG or TGA) we upload certain image to Second Life, that image will always use exactly the same amount of graphics memory depending only on its pixels size and bit depth.

The amount of graphics memory a image uses is shown here:

http://wiki.secondlife.com/wiki/Texture_sizes

For example:

32 bit 1024 x 1024 will consume 4 MB graphics memory (32 bit image has alpha channel)

24 bit 1024 x 1024 will consume 3 MB graphics memory (24 bit image does not have alpha channel)

Some people think that by uploading images in lossy JPG format will consume less memory. I guess their reasoning is "it has smaller size on disk, so it must consume less memory".

Well, image rendering on screen does not work with compression, a pixel is a pixel. That pixel will always use the same amount of graphics memory. Unfortunately those people are just unnecessarily reducing the details in their image by doing this. First they loose detail in JPG compression. When uploaded to SL, there is second compression as the viewer converts the file to JPEG2000 format (the format what SL internally uses to save the file).

So it's always best to upload either TGA or PNG, both retain the image quality. Then there is only one compression when uploading (the conversion to JPEG2000 format) instead of two compressions.
