Daniele, It sounds like you are using WinFract (the DOS Fractint limit is 32768x32768 using disk video, or is based on the available video memory). There is an arbitrarily set maximum of 2048x2048 pixels for the image size in WinFract. I modified my version to use 4096x4096. There is a lack of memory problem that prevents this from working at 4096x4096. However, I was able to generate an image at 3072x2304. I will need to look into this further. Also, there are supposed to be scroll bars on the window that don't appear for some reason. Jonathan
Daniele, the original DOS version of Fractint had a resolution limit of 2048 pixels. However it also has a means of generating multiple images and piecing them together, see the documentation. I believe this effectively overcomes the limit. (Sorry for not being more specific, it's been a while since I looked at this.)
Rich Thompson has created a Windows version that may overcome that limit.
You didn't mention which version you are using. I am cc'ing both Jonathan Osuch, who has been mainting the current version, and Rich. However my suggestion would be to join the mailing list at:

since there are many people who could help you better than I can.

Dear Tim Wegner, I'm a mathematician from Pisa, Italy. Let me tell you how glad I am finding a new update of FractInt for Windows Vista. Indeed this program means a lot for me since I was just a kid when it was released and I grew up with its fractal. Most of my love for mathematics probably came from it.
Anyway, I got a problem with the maximum resolution of Fractint. Indeed I would need some fractals in higher resolution (more then 2048x2048). I saw in some post of yours that the max resolution 2048 is crucial. Is there any way to avoid this limit?
Thank you for your answer Best Kinds
Daniele
