I've done a little math: you've loaded a 240x320 24bit BMP; The same amount of space would be required to hold 300 16x16 images or 133 24x24 images.
I think you're kind of miss-using MS's TImageList if you add large (240x320 is large) images to it. This control is designed to efficiently hold SMALL images (16x16 / 24x24 / 32x32) - the kind of images one usually uses for menus and toolbar buttons. It's deffinitivley NOT a repository for splash-screen-sized images! Again, given it's purpuse, it's only natural it only holds BMP's. If it would hold JPG's it would probably need to turn them into BMP at run time and cache them any way. Also I don't think a 16x16 256 colors bitmap would compress very well when turned into a JPG. One last thing: While the increase in your exe size is difficult to understand, the increased COMPILE time has nothing to do with TImageList and has allmost everything to do with Borland's DFM files! You'll have the SAME problem trying to store 5,6 Mb of ANYTHING into a DFM! (Guess DFM was not designed as a file repository...)
