hello. I'm still pretty new to idl, so bare with me. I'm trying to read a load of .fits files, plots those files and then save the plots using the write_jpeg function. But I'm trying to do it all inside a loop so that it reads a file -> saves the plot ->reads next file ->saves that plot.. etc. But when it writes a new jpeg file, it overwrites the previous one and I want to save them all in the same directory with names image1, image2, image3.. etc. What is the write_jpeg syntax for this? Thanks
