Having trouble uploading a picture, 150x150? Constantly says the image is too big to upload =(
Probably the file size, (cannot be bigger than 6MB) try resizing it.
edit: ^that's if you're uploading to here. If you mean with avatars and signatures take a look at the rules
QUOTEImages, Avatars & Signatures
Avatars and signatures are available for members to personalise their posts by adding their own custom images or text. Do not abuse this right, or it will be removed.
Your posted and linked images, avatars and signatures are constantly reviewed by the moderating staff. Images or content that the GBAtemp Staff find are too big or that are deemed inappropriate including obscene, pornographic, vulgar and any other distasteful or sexually explicit material will be censored, edited or removed with OR without notice; and may result in the member being warned, suspended or banned.
Users are prohibited from posting transparent/invisible images that stretch the page, and the flash-based "screamers" and 1x1 pixel flash videos. Dynamic and HTML-based images, as well as those with overly long animation sequences are also disallowed in your avatars and signatures.
The following image is an example to help you understand the maximum size of a signature. You may go under and but NOT over the 500x150 pixel guideline. No exceptions.
If you see scroll bars in a signature space, that signature is over the maximum dimension limit.
Unlike the resolution of the main signature graphic, there are no set file size limits per image.
[*]The maximum combined file size for all graphics in a member's avatar and signature is: 80Kb
Members may distribute this 80Kb however they wish (Example: 30Kb avatar/50Kb sig, 50Kb avatar/25Kb sig, etc)
