Thanks for doing this properly!
Remember – you want your images to be <=100kb. If it’s for the blog, resizing it to around 1000-1200 pixels wide will be fine.
If you don’t have Photoshop on this computer, it will be on one of the work ones for sure. Taking the time to resize the image makes your post load so much quicker – it’s definitely worth the effort.
