I cannot count the amount of times that I have been in a lesson where a student has come up to me and said they cannot save their work because they have ran out of space on their area. 9 times out of 10 the reason is that they have saved numerous images to their area and have not check the size of the file. I recently discovered this quick and easy to use web tool that allows you to right click an image and select what size you want to make the image have a look at the inserted image for the options available. you can chose to overwrite an image or just replace the image with your chosen size.
Here is a step by step guide for Photo Gadget:
Note: Photo Gadget integrates with Windows Explorer so you will not start it like other programs. To use Photo Gadget after successful installation simply follow instructions available here:
Select your pictures in Windows Explorer.
Right-click on any picture file and choose Photo Gadget Picture Resize.

I use this program every single day and would be lost without it! To get Photo Gadget please follow this link.
