Hello,

I am trying to get an img file from a server. To make it clear, I want to query a DB which will give me the filenames of images I must use, but these images are in a diferent computer, but in the same network. So lets sabe 192.168.1.0 is the network, and .3 is the master and .4 the slave. This slave must query a database that's is .5 (no problem with that) and the files are in .4/home/images/file_XXX.jpg. How can I get those images using ROS.

I am using Ubuntu 18.04 / Ros melodic / python3.

Thanks in advance.

This questions is not really ROS related. just think how you would do this 'normally'? So .4 must be able to serve the images (it's a server so no problem there), .3 must be able to get the image, so just make a request to .4.
