thanks so much it finally worked !!!
Is there an easy way to download (6Kb) bmp (from a/my internal server) and throw them out of memory when no longer needed?
What I assume (Please verify) is that it is not possible to write to SPIFFS during runtime, only during setup phase. Since i can't store the 1500+ images directly to SPIFFS since it's total size is more than 5MB, i was thinking that I simply download the images I need while they're being seen (silhouettes of the airplane) and store them on SPIFFS. I don't think I will ever see all the 1500+ Airplanes on the device so that's not a problem.Everyime I download the images during runtime it resets and throws a stack trace on the serial interface. The images are ok since storing (a few ofcourse) of them to SPIFFS directly and show them on the display works.I am ok with storing them into ram but well, i can't find any examples for it.
