Photo resizing form and accessibility

[Leif K-Brooks]

I'm adding a photo album to my website. The photos have decent
descriptions, so that isn't an accessibility problem. The thing is, I
want to have a form for seeing the photos at a different size, and that
would be meaningless to a blind person. What would be the most
accessible way to put the form?

Usually forms are not used -- you make the image a link, or
put a normal text link near the image. The alt information
gives the accessibility, so it should be filled
out meaningfully.

whats wrong with links to the different sizes?

I have a script resizing the image, and I would like the user to be able
to choose any size.

I have a script resizing the image,

i'd like to see that, all the resizing scripts i've seen do a very poor
job.

and I would like the user to be able to choose any size.

i don't understand what this has to do with accessibility.

I have seen a couple using the GD Lib I think, they seem to do it fairly
well.

Small image = less bandwidth yet people with poor eyesight may have
trouble seeing it

Big image = LOTS of bandwidth and would be pointless for all people,
like poor dialup users (me)

the initial image would just need to be a balance between the two. a
reasonable quality image of about 600x400 is only about 30k (depending
on what the image is). as well as the image size allow the quality level
to be adjusted. simple.

A blind person would be able to hear the description, but a size
selection form would be meaningles to them.

selection form would be meaningles to them.

no it wouldn't. they just wouldn't bother using the form and there is
nothing stopping them sending the pic to a sighted person and would want
to select a size. disabled does not necessarily mean stupid.

I'm not sure about that. Wouldn't you be a bit confused by, say, a
volume control when you aren't hearing any audio?

 

[Mark Parnell]

I'm not sure about that.

What, that disabled doesn't mean stupid?

Wouldn't you be a bit confused by, say, a
volume control when you aren't hearing any audio?

Not if my speakers were turned off (or I didn't have any). It would only be
confusing if I thought I should be hearing audio and wasn't. Or I was
hearing it but the volume control didn't have any effect. I doubt blind
people think they should be seeing the pictures.

 

[brucie]

I'm not sure about that. Wouldn't you be a bit confused by, say, a
volume control when you aren't hearing any audio?

no! from asking or past experience if the volume control is over half
way or past number "3" they know they'll get a smack in the head because
its too loud.

from asking or past experience when sending an image to someone perhaps
for them to describe it they would know sally doesn't like images over
200x200px or over 200kb.

you're assuming a blind person is stupid. stop it.

Hi Leif,
Go have a talk to the guy who runs www.pbase.com (Gallery site) Their
software does dynamic resizing which remembers the users last used setting
as they browse the photos. When an image is displayed there is a short list
of size options displayed below it which you can click to change the size
of the image and the browing mode.

Scripts are good for lots of things,
but image resizing on the fly is too
time consuming. The set of images
you're going to use should be done
in advance.

If you had been preprocessing the images with
a script, well, OK --
if the images are not required to be of
a very high quality.

There is no replacement for personal attention
if the images need to be very good.

A lot of visual aspects
of an image change when it is resized.
No script can replace
your eye.

Did you actually read my message? I said that I was wondering about some
accessibility issues with _my_ photo script, which I've already written
most of. What makes you think I need a photo host?

The script caches resized photos when resizing them the first time, so
there shouldn't be too much of a performance hit.

True, but they have looked pretty good so far.

Why on earth do you need instructions for a blind person to "see" the
images?

Do you not understand what "blind" means, grasshopper?

 

[Derek Clarkson]

Actually I did,
Seeing as what you described didn't make much sense I justed elected to
think that you knew what you where doing. I suggested pbase because it
sounded like you where not sure about how to implement a form for multiple
dynamic sizing of photo. Pbase does this so I thought they might be able to
give you some pointers. As with other people posting here, I cannot see why
you are so concerned about supporting people on brail terminals browsing a
graphics document. All they would need is a brief piece of text saying
something like "Picture of x here". Issues of resolution are a waste of
time.

Perhaps you should redefine you request in clearer terms with a bit more
detail.

Many blind people have some ability to see - some may only distinguish
light and dark, some can read if the text is sufficiently large, people
with 'tunnel vision' may be registered blind but can see well within a
limited angle.
