I don't know why I didn't think of that.... Will work on adding that feature now.

it would be good to have a bigger photo view

I've actually got this on my local version, just haven't released it yet because it partially breaks the mobile view. I'll get that fixed up and released later today!

do you have plans to commercialize the website and make some profits from it

Possibly in the future. Right now the costs to run the site are very low(I pay less than $1/mo) so I'm fine just eating it, but as it grows, I've got a few potential ideas on how this can be marketed to generate revenue. Trying to avoid straight up google ads and such like that. But the short answer is long term yes since hosting a lot of pictures isn't cheap.
