We’re still over a week away from the end of the image section closing, making an extension pretty unlikely. Thanks for your patience with the server issues we had this week though! Hard drives are called “hard” because they can be hard to manage, I reckon 
- I want to ask about crediting, I will use some tutorial about Chess (chess puzzle) from Chess Website to be use on my uplift challenge thread. Should I enter the credit as soon as possible when i upload or submit entry of image that use that puzzle, or i can credit it after i finished and upload it with my final image, i mean i submit the credit in one single document with my final image?
Credit the first time you use it, and in the final submission, and that should be enough IMHO.
- About the final image is Ok in tiff 8 bits color depth because i will use gimp for create my final image?
I made the images that I test with in GIMP, so yes :).
Is it ok if the interaction is implied?..as the image has its base in an uplift story ;in the image the aliens appear just trough their ships:)
Implied is OK, but make the interaction clear.
1 has to be under 150 kb wont that ruin alot of the details ,quality?;even tho its only for other cgtalkers viewing…The FTP one has any constraints? image size… folder size ?why even ftp file anyway?
150kB should be plenty; we make higher-quality copies (from the TIFFs) for some public presentation things anyway.
