ok so just done some homework.
Taking the iphone 14 Pro max as a basis, that camera has a 48mp sensor. This means that each image has an approx size of 75mb when uncompressed.
With this in mind, i have just upped the max image size to 96Mb.
HOWEVER.
The site currently has over 100Gb of image files, as we locally store every single image. We will need to start paying for excess storage soon (at the cost of £5 for every 10 Gb PER MONTH) since we have just hit 97% disk space...
Whilst i have implemented as best i can image optimisation and cropping on here (so it Should crop the image to 1200 x 1000 pixels), I dont think images need to be THAT detailed unless we are looking at minute detail here
Thanks
