Gallery images - jpeg or gif?
 

Should a gallery image (that I'm submitting to TGPs) use jpg for the thumbs, or gif? I had a few errors come back from last nights submissions that said their checker tool didn't find any pictures on the page I was submitting, but there are 18 gifs linking to full size jpegs...

Thanks.

I've never heard of anyone using .gif's for gallery images. The file size is usually waaaaay too large and, I may be wrong, but I think .jpg's are a better quality. Both can have their file sizes compressed with free tools but if your images aren't being detected by scripts then yes, change to .jpg's.

I would stick to jpgs only. It's the standard.

GIF's have a limit of 256 colours, which means photographs look extremely poor when converted to .gif - The file size is also usually much higher than a jpg of the same source image and dimensions.

Stick to jpg's even for your thumbnails too :)

GIF is for graphics with fewer than 256 colors - drawings, graphical text such as a logo, etc.
JPG or PNG are used for photos.

As said, Gif for text, jpg for pictures. why the gif thumbs linked to big jpg pictures? Maybe a setting in you thumb/page creator? That might have been what tripped the scanner?
