Captcha is very annoying for the end-user of the system. SecureImage looks decent, but it is definitely crackable. The sample captchas look very easy to me - a computer program would be able to solve them this year. You may want to try something unlike captchas, there are different ways to do the turing test.

Exactly
If you want a un-crackable captcha you'll need to create one yourself or get a Dev to
Most on the market are extremely easy for a computer to crack

I don't understand how those solvemedia ones aren't easily breakable by bots. They don't seem to do much. They are extremely easy to solve and I can't see how they pose a challenge for someone who wanted to break them.

I just try to squint hard as i can and try to make out the captcha and hit enter, usually I miss a letter or type the wrong one so it can be annoying when trying to solve these especially on TOR when the languages are different Shocked

Interestng point about TOR. Solving reCaptcha usually its takes me 10-15 tries... hate it Cheesy

I think http://www.minteye.com/ is best.
I like it because I don't need to use keyboard for it at all!

So this is combination of advertisement and captcha solving? (good idea if so)

Also it unfortunately seems english only.

Yes, it is ad.
What you mean english only? It is picture so I don't think users have to know english, since you don't have to read anything.
Everything users have to do is use that slider to make image look good, and click enter.

There is example of this chaptcha:

I thought there is some description like "Slide this...". But widget you sent seems great!! Surely gonna implement this as one alternative.

Nope.
But you can add your own text above/under it in any language.

Even better. Thank you man.

And btw I have found possibility to change characteristics of securimage (https://www.phpcaptcha.org/documentation/customizing-securimage/).

None of the captchas that involve typing distorted letters into a box are any good. The best captcha I've run on a website involves 9 changeable images, say animals for example and the question will ask the user to 'select all the cats' out of those pictures of animals. Easy for a human to solve and not easy for a bot because the pictures switch position every time.

Visual captchas > text captchas.

Imho partially true. Visual captcha you explain could be cracked after data mining your picture + questions database. That's why I don't beliave in http://sweetcaptcha.com/ I post earlier.

I share this opinion with you. But I would love to be sure about secureImage - do you know about some real break that happened?

This look great - unfortunately it seems it's english only and my clients usually need localized version(as many of their clients don't know english) :-(

I found interesting no-captcha alternative with localization support, but it alos seems to me it is possible to crack it:

The jumbled words are ridiculous to deal with sometimes.

I don't mind the simple image ones with a couple numbers in them.

Whatever replaces the Captcha, I hope it's easier for humans to use than trying to make out whether that's a "d" or a c and an l. That and the time it takes for me to type it in are the only things that are really annoying about it to me.

Hello,
what captcha solution are you using on your sites? I personally hate reCaptcha as I have big problems to read text(bot will probably read it better then me in near future) so I am thinking about SecureImage - do you thnk it's sufficient (= non crackable in short term)
