PNG vs JPGCategory: kupika development

If you are an oekaki artist, you should be familiar with the PNG and JPG format.

PNG = high quality, bigger file size
JPG = smaller but lower quality than PNG

Ideally we should save all oekakis as PNG.
But, our server space is limited and we will soon run out of space if people continue
to create big-sized oekakis.

Thus I have made it this way:
- if an oekaki is < 100KB, it is saved as PNG
- if an oekaki is > 100KB, it is saved as JPG

Unfortunately the decrease in quality is quite apparent.

I am thinking of returning it back to PNG, but... there is the space limitation.
A trade-off must be made and I am not sure which.

Any suggestions?

hmmm this is hard, i think you should have a big post or somehing
that will  tell them maybe you can also tell some of the artist, I
myself only use the regular size,if you spread the word to the artist
of kupika maybe they would make it smaller, i mean i know they will
like them to still have a high quality option,

I think that we should be able to delete our oekakis that we don't
like so there could be more space on kupika! What do you think hina?

lawl i actually didn't knew the difference of png and jpg... O___O; 
maybe... uh just save it to jpg, to save space... Cos this is a penpal
site not an oekaki site anyway but i think a lot will disagree with me

Here is an idea:

After an account (or even individual oekakis) has been inactive for a
specified period of time, you can change its state to inactive. At
this point, oekakis will be changed into small thumbnails., and
various other compression and space-saving ideas will come into

Now, the full size oekakis (and extra data) will be compressed
together, put into a file per-user, and moved to a folder on the site.
You can then download these files to your computer (and delete them
off the site), saving them to a CD or DVD if you run out of space on
your own computer. 

Then, if the user comes back, they will be prompted to reactivate
their account. This will then be put on a list. You'll then upload
those files to the kupika site, and run a script which will go through
them all and reactivate the accounts. Of course, if you haven't had
need to take them off the server yet it might even be done instantly!

That way you can keep space free on the hosting account, but still
retain the data so you don't annoy the users.

Again, might take a bit of work to implement :P But I think it'd work

You can save oekakis in different formats?

I don't really know what this is about since I rarely do Oekakis, but
I can understand about the not knowing which way to turn.

can we change a PNG to a JPG and why is our kupika avatars png?
hina says:   24 July 2007   644923  
technically it is possible to convert PNG to JPG.
avatars are PNG because PNG allows transparency.

neoeno: your idea is neat, but, well, maybe you already guess it: too
much work -.-

Maybe you could make the size limit smaller, then they could be saved
as PNG. I don't know... I'm not good at this. xD

This  IS a difficult choice to make. Mabe you should switch often,
like every month. 

That's just my opinion, if it doesn't help, sorry, I don't really
understand it.^_^

does not coverting decrease the resolution?
and for the avatar, do u store everyones avatar on there acoount of
like a midi were it stores the commands and takes up less space. If so
why not make them in a gif formate?

and, do u have unlimited bandwidth? if so, can u not get a cheap comp
and stream files on there?
