One of the things I often see being moaned about is how to re-size imagery to less than 750kb to fit on here. Whilst there are lots of arguments as to why 750kb is living in the stone age, this isn't our forum, and we don't pay the cost of the storage.
Back in the good old days, I used to hotlink my images from Picasa. Google stopped that service in favour of the vastly inferior Google Photo's (but kept the images and links luckily), so now I upload them to here, 9 at a time on every post!
And I use a bit of software to do that called IrfanView.
First, you need to make a new folder to put all the resized pictures within your project folder
The software itself comes from this amazingly 90's looking website! You need the plugins too for the batch conversion
Once installed and opened, you will see this
Go to file, then batch conversion/rename
In the top right part, navigate to the folder with the pictures in, then select all and press Add (there's an add all button)
They want to be in the bottom box when added
Next, click advanced here to set up the conversion
I won't bore you with what could be done, but this shows what I do, a basic resize and text overlay
OK out of that when done (and save it if it's a good profile, incase you need to re-install the software due to a PC rebuild etc). Then, set the new folder we made earlier as the output directory (you can see I last used this for the DC40 thread)
Find it here. As you can see, you cant make a new folder from this window
