We took special care to let our add-on kick in at the last possible moment before uploaded images are written to disk. This is why almost all special add-ons collecting exif data will still work as expected even with our add-on installed. But the image on the disk will be written without exif data. So if your special add-on has a feature to rebuild (recollect) exif data from stored images, this feature won't work. But it is very easy to make any special add-on working with our exif cache to collect information from there. Ask us for a quote or ask the programmer of the other add-on to change a few lines of code to make it work.
