You should not hold the main thread in a For Next loop. Instead use the job done event to check if another image requires downloading and trigger it from there.

My for next loop is for add search relust,my download start again from jobdone
My question is about dim job
At first i dim a job and initilize that then start download
Now if job success then we must dim a job with same name ? Or is better to use first job and not dim new one?
Which way is fast and use less cpu and ram?

I declare and initialise the Http job in a function each time. I've never had any problem in doing this as I believe it is only stored as a local object and so only held in memory for as long as it is referenced. I could be wrong with my explanation, but as I said I've not had any problems in doing it this way.

ALWAYS create a new instance of the httpjob. You can give it the same name.

Probably because Manfred is fed up of providing examples when they already exist here on the forum (here's one he's written previously!)...

The search tool is very useful, there's lots more examples if you care to search a little
