Hi Sky,
Long time, no see. I hope you are doing well. I'm doing worse than before and then with this situation that I caused, I'm doing whatever I can to not allow myself to fall too heavily into a "funk". I don't want to just waste away in bed. So......computer time! Almost reminds you of "Hammer Time".....for all the oldies out there who remember that song!
Let me add a bit more to what you wrote about clearing your cache. Most computers now will handle more "stuff" then we could ever stuff in there, but not everyone has a good system....and even good systems need to be cleared out.
I have Internet Explorer 7, and this is what I do to keep disk space manageable. As you said, go to the Tools section at the top of the page (where it says file, edit, view, favorites, tools, help).
Click on Tools, and a whole bunch of goodies will drop down. Click on the bottom one: Internet Options.
You will land on the General tab, with other tabs named Privacy, Security, etc. etc. You want to stay on the General tab.
Look down that page and below Home Page it should say Browsing History. That's the sucker you want. Lol.
If you haven't done this before, I suggest you click the Settings link rather than the Delete link first. This takes you to the Temporary Internet Files and History Settings.
For the Temporary Internet Files, I have chosen to check for a newer version of a stored page every time I visit that site. You know how fast even Psych Central changes.
Disk Space to Use for Temporary: Recommended is 50-250. I leave mine at 51. Even if you have your History List cleared, IE continues to track your activity. The browser cache (Temporary Internet Files) saves the content of visited web pages on your hard drive so that when you revisit them, it can avoid downloading them again and load them, much quicker, from the hard drive instead. By default, IE sets aside many megabytes of disk space for this function (the actual amount depends on the size of your drive), but you can reduce or even eliminate the size of the cache. This is where you would look at the Disk Space to Use and the Recommended Amount. You can drop the amount of cache space to its lowest setting (mine is 50, but I just keep it at 51). You can even go to zero, but because the cache really does save time in downloading (even with high speed), you should give yourself 25 MB or so to work with.
Before deleting anything, click on View Files and see how many are going to be shown. Your eyes will probably pop out, especially if you are on the computer a lot and haven't cleared your cache in awhile. I clear mine every day.
At the bottom of that page is the History section. I only keep my pages in History for one day, but you might want to keep it longer.
NOW....you have set up how you want your cache and history to operate. So it is time to do some deleting. I'm sure you have a lot.

You probably won't have to go back here unless you want to make some changes.
Click OK at the bottom of the page, and you will be returned to the General tab again.
Under Browsing History (where you first went), click on Delete instead of Settings.
A Delete Browsing History page will come up. You can click on Delete for every option there, but at the very least you need to Delete the Temporary Internet Files as well as History. Click on Close at the bottom.
You're back at the General tab. Click on Apply if you made any changes or OK if you just did the deletions without changing any options.
And that is how it is done. Sounds difficult, but it's extremely easy. You can even delete a few times per day if you really want to! Lol. Anyways, this will take care not only all the pictures you brought in, but all the other junk from pages you have visited.
Every browser is different, but this is how IE7 works. You will find similar routes on other browsers.
Good luck.
God bless,
Sandy
