@Oxy is correct here, image uploading sites are NOT allowed on InfinityFree.
Yes, the software can be installed through our script installer. But please note that the script installer is provided by Softaculous, and they frequently add new software, including software which isn’t normally allowed on our service.
We do try to keep up with Softaculous to make sure all the software available in it is allowed and works on your account. But I can’t guarantee that all the software in Softaculous works and is allowed.
