My Web Page Looks Weird

[lore_fdelasierra]

Iīve been publishing my web page almost for a year and itīs been really easy but a couple of weeks ago it started to look pretty weird, some letters and images looks bigger and distorsionated, i already tried publishing them back again and it worked just for a few days because the problem came back over again... i dont know if i am doing something wrong, i'm pretty sure i'm publshing it the same way i ever did... HELP!!

Thank you
