I am trying to figure out how I can save a JPG from ESP32 SPIFFS into an array so I can reuse it without reloading. |

The header comments here tell you how to convert a file into an array and then it can be kept in FLASH instead of SPIFFS. Typically Jpeg files are highly compressed and most processors do not have the space to store large decompressed image arrays. Another approach is to avoid an array and render the jpeg into a sprite, then save the meory block. |
