Message Handler - Not Working with Filter.Command & Filter.Photo condition

I am working on a image editing telegram bot - which can perform various functions based on commands like crop , removebg, etc.The idea is to accept single or multiple images from the user and get a command i.e. /crop or /removebg and get the bot to return edited images.

I am using the python-telegram-bot library and I am unable to trigger the message handler dispatcher defined as follows:
dispatcher.add_handler(MessageHandler(Filters.command('crop') & (Filters.photo),crop))
whereas, something like Filters.caption works perfectly fine as below

dispatcher.add_handler(MessageHandler(Filters.caption('crop') & (Filters.photo),crop))
However, it is practically impossible to add captions to each and every image when uploading multiple images.

Sorry, the command is send after the images in a second message?

Yes.

A Message handler handles one update, not several. What you might want is a ConversationHandler setup, or some manual way to keep track of the file ids.

Please avoid posting questions in multiple places at once. If you do, at least directly point that out in the question.
