Hi, I read instructions here for increasing the font size with HTML coding, but it didn't work for me. I want to make the word "Oracles" at the top left-side bigger. It's at 48pt now. Do I put it in a text box, highlight, and then go to Add HTML? Thanks for your help!

It should be enough if you just make the text box active, and then change the font size to that you want, resave, reupload.

OOOps, I see the text is actually an image. It is possible to stretch the image a bit. Make sure you don't stretch it too much so that it gets pixelated.

Since it's an image, it shouldn't be in a text box at all.
You can either click on an image to highlight it and grab the 'handle' to change the size, or use the object properties box to type in the pixel dimensions.
The best way is to get your image to the desired size is to use a photo editing program, then insert it in VSD.
