I am enjoying the Calibre tool. Table of Contents, and text features are doing very well. I am building an E-book of my grandparents' lives and of my late aunt for the family - which contain a lot of pictures. I am starting in HTML.

I am looking for settings (or another way) in Calibre that control image size better. I have already resized the images to be generally the size I wish - and the original HTML specifies the height and width of the images.

However when Calibre converts the HTML to EPUB, it seems to strip the height, width specifications of the images, and then "sometimes" (especially when the ebook is viewed on an iPad), the images are found to have expanded much larger than planned, and are pixelated, and grainy. However sometimes, they are fine, when viewing the eBook on my Samsung Android tablet and also smartphone.

How can I control the sizes of images? How can I inconsistent presentation of pictures (sometimes they explode and sometimes they don't).

Yes, I am using the iPad output profile. (I have experimented with several).
I am viewing the final ePub book on BlueFire Reader on Android, and iPad.
