Maybe something along these lines (advance apologies for the size, tried to hardcode the resize...):
<img src="http://1.bp.blogspot.com/-uIC_BF3rkAs/TsfubU1kuBI/AAAAAAAAGGU/krcf8ivQE1I/s1600/Campfire+Toaster+2.jpg" width='25%'>
Gets you an image that is 25% of the width of the page. Percentages are preferred to pixels for specifying size because everybody has a different screen size.
To re-size images, remember to put the "location" (img src="location") and the pix number of both height and width in quotation marks.
In this case, as the page info (found by right clicking the image and choosing page info) listed dimensions as being 1,600px × 1,443px,
I simply used height="140" width="160", as it seemed handy to divide by ten,
and I wasn't much worried of what distortion would result by my ignoring 43 px out of 1,400.
Hope this helps. There is an current HTML Sandbox page on this site,
though it can take some looking to find it, but one can *usually* do a practice run of whatever html
coding one is trying to implement, and see how the image renders using the "preview" function
found at the bottom of any reply window [on this site, anyway].
* it doesn't work for everything, particularly in regards to multiple images placed to the left, or right, interspersed with text.
Putting all images in < center > is easiest, when using more than one.
My deceased Norwegian mother-in-law had one of those - at least I think that’s where I saw one of these ‘toasters.’
LOL! I remember my grandmother had that toaster when I was a child. Thanks for the memories.
