Saving High Quality images on Dynamic IP user

Not sure if this is appropriate place for this thread, it's about saving high quality images on the browser with Dynamic IP Address.

I used to be a DSL when I was in college, since DSL uses static ip address, downloading images are clean and crisp like PNG. Any image format will do that. However when I switched to Mobile Broadband (since this is the only option in the province where I work), saving images were noticeably degraded (like a JPG format) even if I press CTRL+F5 to load higher. I ask a person who distribute broadband to our town, he explain that Mobile Broadband uses Dynamic IP address and Static IP for DSL, therefore it's a big difference between the two.

I wanna ask if there's a way to save images in high quality on a dynamic ip like it does on DSL with static ip. Thank for reading this!

I am ready to be corrected on this but...

There is no difference between dynamic and static IP. Dynamic is given from a range of IP address pool whereas static is reserved for that particular client again from the same pool.

Can you give a link to what you are trying to save? Maybe you are saving the link of the image and not itself(?).
CTRL+F5 where? in IE it just refreshes the page ignoring the cache.

Any images available from any site will do. Currently using Chrome but other browsers will do the same (FF, IE10 and Opera, all with ctrl+f5).
What I heard from the tips, CTRL+F5 will slightly gives a higher detail image.

Tried in DeviantArt. Do this when you want to save a picture, right click it and go in to properties. What does the dimensions show? Check the file properties for details as well after you download/save.

I did however search for it,

So it seems to be an ISP feature, maybe you can bypass that with ZenMate.

It is browser based VPN and free at the moment. Installed to the browser and doesn't affect any other browsers or your connection. https://zenmate.com/ I had to use this when I couldn't get a reliable Youtube 1080 performance, and it worked great with ZenMate (go figure)

You may have to clean cache if you try to download the same pictures, I am not sure. Try new ones if so too. Experiment

Dynamic IP is just a different way of assigning an IP address and has nothing to do with performance. DSL can use a dynamic IP and that is the most common situation. Most likely your problem is a slow Internet connection.

The key point here is mobile broadband (OP and those in the links I gave all mobile). Seems ISPs implement filtering for images to save bandwidth(?). Unless browsers have a setting somewhere, the zenmate solution seems to be plausible. OP will have to try.
