Near-impossible with that.
The tech you're using isn't designed for reliability nor for long data streams with no error correction or many
repeated transmissions and checksums or your own clever encoding.
Basically no good for typical-sized jpg image files, throw it away. Those modules are worthless generally (unless you're
building something as basic as a remote on/off or something).

What you're actually looking for is 802.11 - get a Arduino Yun, or WiFi shield or something similar, at both ends.
A Raspberry Pi 3 would be ideal, and might end up at a similar cost.

There are other options rather than 802.11, there are more affordable, and are pretty reliable too. You could try Bluetooth with an UART interface, or an 802.15.4 modules like XBee or murata radios.

I agree, but the original poster might struggle.. the simpler option may be just to use a board that already has the relevant bits and stack (i.e. any SBC with 802.11).

All depends on the available libraries. I had a lot work using an EN28J60 wifi module with Arduíno once. The wiznet modules had the default Ethernet library on arduino's IDE. or you were suggesting 802.11 without wifi protocolos?

Perhaps a good approach, if the OP is willing to change hardware, is to list the available options, rank it by price and relliability and than searching the libraries for each modules, so he can know the trade off from which one.
