this blog helped me to make my pictures bigger. after i changed my html, i've not had to resize my pics. i just upload them to photobucket and then i get the html code and copy and paste it into the edit html tab on the new post!!! u can upload up to 250 pics into photobucket and it's much quicker to copy and paste the code into your edit html tab than to upload through blogger. if you want to add text click back on the compose tab and you can view the pics and add text however you wish. hope this helps.
