Adjusted images to allow them to actually be uploaded to a genuine Ender-3 V2 LCD board, which is surprisingly picky.
Description
It is possible to change the boot-up screen of an Ender-3 V2's LCD screen to an alternate image, provided it conforms to certain restrictions. There are included example custom boot-screens to choose from within the repository, however, genuine DWIN display modules (unsure as to other models) have a limitation that all
.jpgimages (such as the boot-screen) must be under 32KB. Most of the images in the repository were greater than this file size limit, and therefore will cause abstract data and corruption if uploaded to the LCD. I have compressed the images in order to fit this file size limit.Benefits
This allows the alternate bootscreens provided in the repository to be functional as drop-in replacements.

I had been discussing this with others in the official Marlin Discord server, as can be seen here: #bugs-chat. Additionally, another member of the server had already investigated the file size limitations in a previous issue here and confirmed my findings.
